Description

The two-Higgs-doublet model with an additional pseudoscalar represents a simplified and ultraviolet-complete model for Dark Matter. It provides a wide spectrum of collider signatures, including a $Z$ or a Higgs boson and missing transverse momentum, with detectable cross-sections at the LHC. In the context of this model, the sensitivity of an existing search of the ATLAS experiment for the signature of a $125$ GeV Higgs boson decaying to two b quarks and missing transverse momentum from Dark Matter particles is discussed. The exclusion potential is estimated using simplified detector-level limits previously published by the ATLAS Collaboration.
